In the schools whither they went, they were not to make confidants of any. Their garments were so prepared as to conceal their greatest treasure,—the precious manuscripts of the Scriptures. These, the fruit of months and years of toil, they carried with them, and whenever they could do so without exciting suspicion, they cautiously placed some portion in the way of those whose hearts seemed open to receive the truth. From their mother’s knee the Waldensian youth had been trained with this purpose in view; they understood their work, and faithfully performed it. Converts to the true faith were won in these institutions of learning, and frequently its principles were found to be permeating the entire school; yet the papal leaders could not, by the closest inquiry, trace the so-called corrupting heresy to its source. The spirit of Christ is a missionary spirit. The very first impulse of the renewed heart is to bring others also to the Saviour. Such was the spirit of the Vaudois Christians. They felt that God required more of them than merely to preserve the truth in its purity in their own churches; that a solemn responsibility rested upon them to let their light shine forth to those who were in darkness; by the mighty power of God’s word they sought to break the bondage which Rome had imposed. The Vaudois ministers were trained as missionaries, every one who expected to enter the ministry being required first to gain an experience as an evangelist. Each was to serve three years in some mission field before taking charge of a church at home. This service, requiring at the outset self-denial and sacrifice, was a fitting introduction to the pastor’s life in those times that tried men’s souls. The youth who received ordination to the sacred office saw before them, not the prospect of earthly wealth and glory, but a life of toil and danger, and possibly a martyr’s fate. The missionaries went out two and two, as Jesus sent forth His disciples. With each young man was usually associated a man of age and experience, the youth being under the guidance of his companion, who was held responsible for his training, and whose instruction he was required to heed. These co-laborers were not always together, but often met for prayer and counsel, thus strengthening each other in the faith.
